BOOTMGR is missing (another Windows version disc available only)

[Jonatas_10]

Hi. I have Windows 10 installed in my computer. A few days ago I tried to resize my partitions and I messed up some configs... I made a mistake and put a partition (the one without OS) as my initializing partition. So when I restarted the computer, it showed up the error: "BOOTMGR is missing... press ctrl+alt+del to restart". Windows 10 won't boot.
It seems an easy fix, but the problem is that I upgraded to Windows 10 from Windows 7, so I just have the Windows 7 disc. Can I use this somehow to fix my problem? Using command prompt or something? I don't have another computer to download Windows 10 ISO and burn to DVD, just a netbook (without CD/DVD drive).

Thanks in advance.

You should be able to reinstall 7 and then re-upgrade to 10. You have already done the upgrade before, so you should be able to do it again.

You can also try using the link below and get Windows 10 (obviously through another computer) and burn it to a CD/DVD or USB.
